Multiple select lists and edit all occurrances

using a cck type as an event with the event and eventrepeat is causing problems with select lists set to allow multiple selections.

If you only choose one item from the select list the submission of the data is fine. However, in editing an existing repeat, selecting multiple items causes the submission process to return a whole bunch of array information, like:

Array ( [0] => field_description_value [1] => field_description_format ) Array ( [0] => '%s' [1] => %d ) Array ( [0] => field_description_value = '%s' [1] => field_description_format = %d ) Array ( [0] => dissertation seminars [1] => 3 [2] => 51 [3] => 51 ) Array ( [0] => field_location_value ) Array ( [0] => '%s' ) Array ( [0] => field_location_value = '%s' ) Array ( [0] => SHR 210 [1] => 51 [2] => 51 [3] => 0 ) Array ( [0] => field_location_value ) Array ( [0] => '%s' ) Array ( [0] => field_location_value = '%s' ) Array ( [0] => SHR 211 [1] => 51 [2] => 51 [3] => 1 ) Array ( [0] => field_description_value [1] => field_description_format ) Array ( [0] => '%s' [1] => %d ) Array ( [0] => field_description_value = '%s' [1] => field_description_format = %d ) Array ( [0] => dissertation seminars [1] => 3 [2] => 48 [3] => 48 ) Array ( [0] => field_location_value ) Array ( [0] => '%s' ) Array ( [0] => field_location_value = '%s' ) Array ( [0] => SHR 210 [1] => 48 [2] => 48 [3] => 0 ) Array ( [0] => field_location_value ) Array ( [0] => '%s' ) Array ( [0] => field_location_value = '%s' ) Array ( [0] => SHR 211 [1] => 48 [2] => 48 [3] => 1 ) Array ( [0] => field_description_value [1] => field_description_format ) Array ( [0] => '%s' [1] => %d ) Array ( [0] => field_description_value = '%s' [1] => field_description_format = %d ) Array ( [0] => dissertation seminars [1] => 3 [2] => 49 [3] => 49 ) Array ( [0] => field_location_value ) Array ( [0] => '%s' ) Array ( [0] => field_location_value = '%s' ) Array ( [0] => SHR 210 [1] => 49 [2] => 49 [3] => 0 ) Array ( [0] => field_location_value ) Array ( [0] => '%s' ) Array ( [0] => field_location_value = '%s' ) Array ( [0] => SHR 211 [1] => 49 [2] => 49 [3] => 1 ) Array ( [0] => field_description_value [1] => field_description_format ) Array ( [0] => '%s' [1] => %d ) Array ( [0] => field_description_value = '%s' [1] => field_description_format = %d ) Array ( [0] => dissertation seminars [1] => 3 [2] => 50 [3] => 50 ) Array ( [0] => field_location_value ) Array ( [0] => '%s' ) Array ( [0] => field_location_value = '%s' ) Array ( [0] => SHR 210 [1] => 50 [2] => 50 [3] => 0 ) Array ( [0] => field_location_value ) Array ( [0] => '%s' ) Array ( [0] => field_location_value = '%s' ) Array ( [0] => SHR 211 [1] => 50 [2] => 50 [3] => 1 ) Array ( [0] => field_description_value [1] => field_description_format ) Array ( [0] => '%s' [1] => %d ) Array ( [0] => field_description_value = '%s' [1] => field_description_format = %d ) Array ( [0] => dissertation seminars [1] => 0 [2] => 53 [3] => 53 ) Array ( [0] => field_description_value [1] => field_description_format ) Array ( [0] => '%s' [1] => %d ) Array ( [0] => field_description_value = '%s' [1] => field_description_format = %d ) Array ( [0] => dissertation seminars [1] => 0 [2] => 54 [3] => 54 ) Array ( [0] => field_description_value [1] => field_description_format ) Array ( [0] => '%s' [1] => %d ) Array ( [0] => field_description_value = '%s' [1] => field_description_format = %d ) Array ( [0] => dissertation seminars [1] => 0 [2] => 88 [3] => 88 ) Array ( [0] => field_description_value [1] => field_description_format ) Array ( [0] => '%s' [1] => %d ) Array ( [0] => field_description_value = '%s' [1] => field_description_format = %d ) Array ( [0] => dissertation seminars [1] => 0 [2] => 89 [3] => 89 ) Array ( [0] => field_description_value [1] => field_description_format ) Array ( [0] => '%s' [1] => %d ) Array ( [0] => field_description_value = '%s' [1] => field_description_format = %d ) Array ( [0] => dissertation seminars [1] => 3 [2] => 617 [3] => 597 ) Array ( [0] => field_location_value ) Array ( [0] => '%s' ) Array ( [0] => field_location_value = '%s' ) Array ( [0] => SHR 210 [1] => 617 [2] => 597 [3] => 0 ) Array ( [0] => field_location_value ) Array ( [0] => '%s' ) Array ( [0] => field_location_value = '%s' ) Array ( [0] => SHR 211 [1] => 617 [2] => 597 [3] => 1 ) Array ( [0] => field_description_value [1] => field_description_format ) Array ( [0] => '%s' [1] => %d ) Array ( [0] => field_description_value = '%s' [1] => field_description_format = %d ) Array ( [0] => dissertation seminars [1] => 3 [2] => 618 [3] => 598 ) Array ( [0] => field_location_value ) Array ( [0] => '%s' ) Array ( [0] => field_location_value = '%s' ) Array ( [0] => SHR 210 [1] => 618 [2] => 598 [3] => 0 ) Array ( [0] => field_location_value ) Array ( [0] => '%s' ) Array ( [0] => field_location_value = '%s' ) Array ( [0] => SHR 211 [1] => 618 [2] => 598 [3] => 1 )

This is all that appears on screen. Checking the node, however, shows that the data (including the multiple selects) have been stored correctly in the database.
